The present disclosure is directed to a system for providing substantially 180 degrees, or more, of rotation between a sheet metal door mounted on a sheet metal sidewall of a chassis, relative to the chassis. The system includes a first and a second shaft passing through a module positioned between the door and the sidewall, whereby the door rotates about the two shafts, where the two shafts are not axially aligned. The chassis may hold sleds of a server, and the door may further comprise multiple linking modules, such that the sleds are coupled to the linking modules when the door is in a closed position, and the sleds are slid home within the chassis.

Disclosed is an air conditioner including a first frame including a through hole, a second frame rotatably coupleable to the first frame, the second frame including a burring portion at least a portion of which is insertable into the through-hole in a first direction, where while the burring portion is inserted into the through-hole of the first frame, the burring portion protrudes in the first direction, and a burring hole formed by the burring portion, and a fastening member insertable into the burring hole in a second direction opposite to the first direction and configured to function as a rotary shaft of the second frame, where while the fastening member is inserted into the burring hole, the fastening member protrudes in the second direction.

The invention relates to a high-voltage device (14) for a high-voltage application. The high-voltage dev ice comprises an electrically insulating housing (15), having a housing cover (16) that covers a housing interior (18), and covering means (10) for at least one electrical terminal (34) or electrical region to be protected from touching, which covering means are arranged in the housing interior (18). The covering means (10) have a protective cover (26). The protective cover covers the electrical terminal (34) or the electrical region, can be locked in a closed position by means of at least one locking element (30) and can be transferred into an open position by means of an opening operation. The at least one locking element (30) for the protective cover (26) within the housing is designed in such a way that the release of the at least one locking element requires a duration, the electrical terminal (34) or the electrical region having transitioned into a touching-safe state after said duration has elapsed following the opening of the housing cover (16) and following the interruption of the high-voltage circuit triggered by the opening of the housing cover.

An electronic device is provided. The electronic device includes a hinge housing extending in a direction of a rotational axis, a first housing connected to one side of the hinge housing in a direction perpendicular to the rotational axis to rotate about the rotational axis relative to the hinge housing, a second housing connected to an opposite side of the hinge housing in a direction perpendicular to the rotational axis to rotate about the rotational axis relative to the hinge housing, and a flexible display including a bending area at least partially disposed in the hinge housing and formed to be a flat surface or a curved surface, a first area extending from the bending area in one direction perpendicular to the rotational axis, and a second area extending from the bending area in an opposite direction perpendicular to the rotational axis.

In an embodiment, an electronic device may include a housing including a hinge module, a first housing, and second housing. The first and second housings are rotatably coupled to each other via the hinge module to be in a folded state or an unfolded state. The electronic device may further include a flexible display, at least one conductive pattern disposed in the first housing, at least one conductor disposed at a position in the second housing corresponding to the at least one conductive pattern such that the at least one conductor is capacitively coupled to the conductive pattern when the electronic device is in the folded state, and a wireless communication circuit electrically connected to the at least one conductive pattern in the first housing. Other embodiments are also possible.

A hinge module is provided, including a positioning assembly, a first shaft, a second shaft, a first bracket, a second bracket, and a switching assembly. The first shaft has a first rotating part and a first installing part. The first rotating part is rotatably disposed through the positioning assembly. The second shaft has a second rotating part and a second installing part. The second rotating part is rotatably disposed through the positioning assembly. The first bracket is disposed on the first installing part of the first shaft. The second bracket is disposed on the second installing part of the second shaft. The switching assembly is movably disposed in the positioning assembly and abuts between the first shaft and the second shaft. The hinge module is adapted to switch between a closed state, a first unfolded state, and a second unfolded state.

Examples of devices with foldable display screens are described. In an example, the foldable display screen of the device includes a first portion, a second portion, and an intermediary portion between the first portion and the second portion. The device further includes a hinge joint coupled to the first portion and the second portion to fold the first portion and the second about the intermediary portion. Further, the device includes an actuating block abutting the intermediary portion and the hinge joint. The actuating block, in response to receiving a pressing force from a user on the intermediary portion above the actuating block, is to cause the hinge joint to operate and fold the foldable display screen.

A rotating shaft apparatus and an electronic device are provided, which include a first rotating mechanism and a second rotating mechanism. The first rotating mechanism includes a first ratchet and a first tooth. The first tooth can rotate with respect to the first ratchet in a first rotation direction. An engagement structure between the first tooth and the first ratchet makes the first tooth stop rotating in a second rotation direction. The first and second rotation directions are opposited. The second rotating mechanism is arranged coaxially with the first rotating mechanism, and includes a second ratchet and a second tooth. The second ratchet is in stop-rotation connection with the first tooth. The second tooth can rotate with respect to the second ratchet in the second rotation direction. An engagement structure between the second tooth and the second ratchet makes the second tooth stop rotating in the first rotation direction.

A metal enclosure for electrical components may include a rear panel and four side panels coupled with adhesive to form a bonded case having a cavity with a front opening. Channels of the four side panels may be joined to form a case channel circumscribing the opening. The case channel may be recessed towards a center of the opening so as to not extend radially beyond an envelope formed by planes of main panes of the four side panels of the one of the two adjoined panels or the one of the two separate panels. A door may be hingedly connected to one of the four side panels and may have one or more latches installed thereon. When the door is closed, a gasket engages a main panel of the door and a front surface of the case channel to seal the metal enclosure.

A cradle includes a main body having a seating portion in which an earbud is seated, a folder body capable of being converted between a closed state and an opened state of the seating portion, and a hinge portion configured to couple the folder body to the main body, wherein the hinge portion includes a first hinge coupled to the main body, a second hinge coupled to the folder body, a shaft extending through the first hinge and the second hinge, a first magnet coupled to the first hinge, and a second magnet coupled to the second hinge or to the folder body, and wherein the first magnet and the second magnet maintain a repulsive force therebetween while the folder body is converted into the opened state from the closed state. The semi-automatic opening structure of the cradle is simplified so as to simplify the manufacturing process and reduce manufacturing costs.
